SPECIFICATION forming part of Letters Patent No. 299,068, dated May 20,1884.

Application filed October 10, 1883. (No model.)

.To @ZZ whom t may concern.-

Be it known that I, JOHN A. GRIswoLn, a citizen of the United States,residing in the city and county of San Francisco, State of California,have made and invented certain new and useful Improvements in Shippingand Service Cans for Lubricating and Burning Oils, and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings and lettersmarked thereon.

My invention relates to a can or receptacle adapted to contain oils incondition suitable for shipment or storage, and when required for use tobe converted into a servicecan from which the contents can be drawn ordischarged in quantities, as desired. In such form or arrangement ofparts it serves as a perfect distributer for lubricatingoils and likefluids and as a safe lamp-lling device for burning-oils. In itsprincipal features and arrangement of parts as a lamp-iilling device itis an improvement upon the Letters Patent granted to me on the 8th dayof February 187 6; but it differs from that device in that the partsconstituting the discharging apparatus are greatly simplified, and areaccessible for repairs; that the stream of oil at the time of dis chargecan be more exactly regulated and can be cut off at any point, and thatthe can is readily closed up at all outlets for shipment.

The following description fully explains the nature of my saidimprovements and the manner in which I proceed to construct, apply, anduse them, the said drawings being referred to by iigures and letters, asfollows:

Figure l is a side elevation of the can. Fig. 2 is a vertical sectionthrough the can, showing its adjustment for use as an oiler. Fig. 3 is asection of the top of the can when it is in condition for shipment. Fig.4L shows the cutoff spout and oiling-nozzle. Fig. 5 is a nozzle toreplace the oiling spout and nozzle when the can is used as alamp-filler.

A represents the body of the can, preferably of cylindrical form.

B is asmall cylinder, open at the top, and with inlet b leading outofthe bottom.

C is a discharge tube or passage leading from the lower part of thecylinder B up to 5o the top of the can and terminating in ascrewthreaded socket or coupling, c, for connecting a nozzle. Thisconducting passage can be placed either on the outside or the inside ofthe can.

D is a handle for convenience in carrying the can about.

E is a loose disk or clapper-valve covering the inlet b, and kept to itsseat, or limited in its vertical play by the piston playing above it. 6o

F is a piston fitting closely in the cylinder, and operated by a rod orstem, F', that cxtends up through the top of the can. This rod isoperated in one direction by pressure, and in the opposite direction bya coil-spring, f, of suitable strength bearing upon the top of the canat the lower end and under the head H at the upper end.

his a screw-threaded neck or rim around this top opening of the can, towhich a screw- 7o cap is iitted.

I is a filling-aperture closed by ascrew-cap, removable to permit thecan to be filled.

K is a small removable cut-off faucet with a valve, k2, operating in onedirection by press- 7 5 ure on the head la", and in the other directionby a spring, L.

7c is a spout adapted to receive the tube or nozzle M, of greater orless length and of straight or curved shape.

M N illustrate two forms of nozzles to be attached to the outlets c or7c. The one, M, in connection with the spout, converts the can into anoiler. The other one, N, is a simple nozzle for use Without the spout L,for filling 8 5 and emptying lamps and vessels.

The top of the can is provided with a screwthreaded neck, a., and aremovable top, G, is screwed thereon. The rim h is provided on the topG, and also the filling-aperture I.

The cylinder B is fixed in place on the bottom of the can A by means offeet d d, to give clear space beneath and around the centralinlet-aperture, b, in the bottom of the cylinder.

The valve E is a metal disk having a leather 9 5 or other pliable washerfixed to the rim.

is dropped loosely into place from above before the piston is inserted,and, being of about the same diameter as the cylinder` it plays up anddown without guides.

The outlet from the cylinder is a fixed metal tube, C, that may becarried to the outside of the can, or be fixed inside the can-body. Inboth cases thc end will project from the can to afford means ofconnecting a discharge nozzle or spout. This end c is screw-threaded tore ceive a cap or plug to close the outlet and to afford connection forthe spout and nozzle.

The pistou F is a disk of wood, having a circumferential groove in itsrim to receive a strip of felt or other suitable material, to form apacking.

The aperture in the top of the can for the piston-rod is screw-threadedto receive a cap. The piston-rod can be pressed down into the can andthe aperture tightly closed. This affords a means of sealing up the canand securing the contents in condition for shipment, or to preventevaporation, or to close up the can when not required for use.

y In all devices or apparatus of this character,

the cylinder and piston constitute a means of forcing out the liquidcontents in quantities or charges. The detachable nozzles enable the canto be used as a lamp-iiller, and to be converted into an oiler or adistributer for lubricating-oil. `The particular construction of theseparts also greatly reduces the cost of manufacture, and contributes,besides, to the durability of the apparatus.

-rWhen used for distributing oil for lubricating purposes, the pistonrenders effective service in forcing the oil through a length of nozzleto such points and localities in and about machinery that are difficultof access. The discharge of oil is then independent of the position ofthe can, and will take place even while the end of the nozzle is held inposition above the supply. With a long spout o-r nozzle overhead workcan be reached, and a curved nozzle can be employed to apply oil to manypoints now practically inaccessible by ordinary oilers.

As the operation of the pressure or forcing device is such that whenonce the cylinder-B is charged and pressure is maintained by hand on theplunger-head, the ilow of oil will continue until the cylinder isemptied. I provide and employ a cut-off to be used in connection withthe oiling-nozzles. This cut-off consists of the spout or faucet bodyK,having its lower end screw-threaded to iit the outlet c, and providedwith a spout or outlet end to receive the tube or nozzle M.

In the body K is a plunger-valve having a stem, k2, carried out throughthe top and furnished with a head, 7c3, below which is fixed acoil-spring, L. Pressure upon the head 7c3 forces the valve down acrossthe outlet through the spout and cuts off the supply,while the springopens the valve,when this pressure is removed. This cut-off is useful incontrolling the outlet when the nozzle is turned down to reach pointsbelow the position in which the oil-receptacle is held. This valve orcutoff is not required when the can is used as a lamp-filler when itsplace is occupied by the curved spout N.

To put the can in condition for use, the caps over the apertures c hareunscrewed. The nozzle N is then screwed into the outlet c, and theapparatus is ready for use.

The spring f may be dispensed with, as rod F may be worked altogether byhand.

The advantage of using the spring is that it recharges the cylinder B asoften as vit is emptied, and for this purpose it is more especiallyuseful in working the apparatus as an oiler, for it enables the supplyof oil to be controlled and the rods F 7a2 managed with one hand.

As thus constructed my improved can constitutes a simple, efficient, andvaluable article for shops, factories, and the household.

Illuminating and lubricating oils and many fluids and liquids attendedwith more or less risk and danger to life and health can be handled in asafe manner. n

The can -or holder A is made of different sizes, according to thequantity of oil it is required to contain. Those for stores and largeestablishments, where the consumption of oil is greater, will beconsiderably largeriu capacity than those provided for householdpurposes and for use as oilers.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. The combination, with the can or holder A, of the fixed cylinder withvalved inletb, piston F, and rod F', fixed outlet tube or passage O,terminating'in the socket or coupling c, head or handle H, to operatethe piston-rod from the outside ofthe can, and the cut-off spout K, withvalve and valve-spring, substantially as hereinbefore described.
